E.g., humans have a choice in the matter, but cows are too
stupid to even understand such a choice. I completely agree.

If accident befalls them, then there is no reason to tamper with
their memories at all. Otherwise, rather than letting them terminate
themselves (as they're sure to do again), either talk them out of
choosing self-destruction, or instantiate a version of him or her that
will be as close as possible to the original, but will want to keep on living.

Some human entities will not choose such a thing, what I
call a "path of personal evolutionary progress". Take a
devout traditional religionist. There's nothing wrong with
giving him his 1mm^3 of the material resources he requires,
and the 1 second per real second of runtime [1] he requires,
to live as he wishes indefinitely.

Right. Which is why I amended your #5.

I wouldn't call it a farce, exactly, but I know what you're getting
at and I agree completely. Silicon/diamondoid on Earth alone will
provide ample and relatively incredibly small resources per
individual human (as they're now constituted), and it would be
greedy and unappreciative of the FAI to do anything less for humans.

Now the question of how much resources should more advanced and
ambitious humans receive is a vastly harder question. Perhaps as much
as an entire cubic meter, at 1sec/sec of processing. But we can leave
that, conveniently, to the FAI.
